The embodiment further illustrates that the IoT device of the present invention obtains the dynamic IoT address 18 by using the virtual communication protocol 10. method.

The IoT master 60 is provided with a TCP/IP protocol 22; an IoT device 32 is provided with a TCP/IP protocol 22. Before the virtual communication protocol of the IoT device 32 is established, the original TCP/IP communication protocol needs to be established, and a common DHCP (Dynamic Host Configuration Protocol, DHCP for short) is taken as an example. The IoT device is used as an example. 32 needs to request a dynamic network IP address from a DHCP server (a host on the network or the IoT host 60). For the IoT device 32, the dynamic network IP address is a TCP/IP protocol. The source address 23 in 22 can obtain communication and data exchange with the IoT host 60 after obtaining the dynamic network IP address.

After obtaining the dynamic network IP address, the IoT device 32 can only perform general TCP/IP protocol-related applications with the IoT host 60, if the IoT device 32 wants to use virtual communication. When the protocol 10 is connected to the IoT function of the IoT master 60, the IoT device 32 must connect to the existing TCP/IP protocol and send a request for the dynamic IoT address 18 (or code) to the IoT. The master terminal 60. At this time, the IoT master 60 will allocate a dynamic IoT address 18 suitable for the IoT device 32 to the IoT device 32.

The IoT source address 19 in the (IoT Protocol).

For example, initially the IoT device 32 does not have an IP, so the entire network is broadcast to ask who can assign an IP to him. The IoT host 60 has a function of dynamically allocating IP by DHCP, so a set of IP is transmitted to the IoT device. 32 is used, so the IoT device 32 obtains a dynamic IoT address 18 with an IP of 192.168.1.2 (for the IoT device 32, the dynamic network IP address is the source address in the TCP/IP protocol 22 23), and know that the IP of the IoT host 60 is 192.168.1.1. For the IoT device 32, the IP address is the target address 25 in the TCP/IP protocol 22).

The IoT device 32 then uses 192.168.1.2 as the source address 23 and sends a data asking for its own IoT address to the IoT master 60 with the target address 25 of 192.168.1.1. The IoT master 60 receives the request and transmits the source address of 192.168.1.1 to the IoT device 32 of 192.168.1.2, an IoT address named enddevice01, which represents the IoT device 32 in the virtual communication protocol. IoT address.

In this embodiment, thereafter, the IoT command sent by the IoT device 32 to the IoT host 60 is carried on the network packet of 192.168.x, which contains the virtual communication protocol 10 (IoT protocol). The content, that is, the IoT instruction including the transmission address (IoT source address 19) is enddevice01, and the delivery address (IoT destination address 20) is, for example, the IoT instruction of manager01, and the IoT instruction to be executed by the device for the address of the address. Or request 21.

Therefore, a packet transmitted from the IoT device 32 to the IoT host 60, which is transmitted by the virtual communication protocol, is referred to herein as a first message packet, and the first message packet includes at least the following architecture: "Virtual Protocol 10 (IoT Protocol):

1.IoT source address 19: enddevice01

2.IoT target address 20: manager01

3. IoT instruction or request 21: read temp

Physical Agreement (TCP/IP Protocol 22):

1. Source address 23: 192.168.1.2

2. Target address 25: 192.168.1.1"

The above description, in other words, an IoT device 32 is connected to an IoT host 60 by the entity communication protocol to which it belongs, and sends a request for IoT address information to the IoT host 60, and then the IoT master The console 60 distributes a unique dynamic IoT address 18 to the IoT device 32.

After the IoT host 60 delivers a unique dynamic IoT address 18 to the IoT device 32, the data transmitted by the IoT device 32 to the IoT host 60 is a first message packet, the first message. The packet includes a physical communication protocol to which the IoT device 32 belongs and a virtual communication protocol 10 disposed at a position corresponding to the layer 7 application layer of the OSI model. The virtual communication protocol 10 includes an IoT source address 19 and an IoT target. Address 20 and at least one IoT command or request 21; wherein the IoT source address 19 is the dynamic IoT address 18 of the IoT device 32, and the IoT target address 20 is the IoT device 32 communication destination target IoT device 32 A dynamic IoT address, the IoT instruction or request 21 is an instruction or request that the IoT device 32 is to be executed by the communication destination device.

The foregoing dynamic IoT address 18 means that the IoT host 50 can dynamically reconfigure a new address or code for an IoT device 12, and the new address or code is the dynamic IoT address 18. After the IoT device 12 is started or enters the Internet of Things of the IoT host 50, the IoT host 50 will issue a dynamic IoT bit via the IoT device 12 requesting the IoT host 50. The address 18 is given to the IoT device 12, which is very useful for frequently changing the IoT devices 12 in an Internet of Things, enabling the IoT master 50 to be fully managed to each IoT device 12 of the Internet of Things.

This embodiment illustrates how the IoT device 32 communicates with the target IoT device 72 and transmits an IoT command to the shutdown device.

Before the establishment of the virtual communication protocol 10, the IoT device 32 obtains the IoT address enddevice01 from the IoT master 60 via the TCP/IP protocol 22, as in the method shown in FIG. 2. Similarly, the target IoT device 72 transmits The Zigbee standard protocol 24 obtains its IoT address enddevice02 from the IoT master 60.

After the virtual communication protocol 10 is established, when the IoT device 32 is to transmit an IoT command to the target IoT device 72, it transmits a packet (ie, the first message packet) to the IoT host through the TCP/IP protocol 22. 60. In addition to the original TCP/IP protocol 22 related information (source address, target address, etc.), in the data of the application layer of the TCP/IP protocol 22, the first message packet is marked with the packet from the packet. Enddevice01, the receiver of this packet is enddevice02, and this IoT instruction is to shut down the device.

After the IoT host 60 receives the first message packet transmitted by the IoT device 32 to itself, it checks the data discovery in the virtual communication protocol 10 of the application layer of the TCP/IP protocol 22, and the packet receiver For enddevice02. Therefore, the first message packet is deducted from the pure application layer data source address 23 of the TCP/IP protocol, and the target address 25 is transferred to the Zigbee standard communication protocol 24.

Before the transmission, the data of the Zigbee standard communication protocol 24 (source address 73, target address 74, etc.) is added in front to enable the target IoT device 72 to receive the communication message, and the process is passed through the purple bee. The standard communication protocol 24 transmits the packet to the target IoT device 72, including the contents of the virtual communication protocol 10, which in this embodiment is a second message packet.

When the target IoT device 72 receives the second message packet sent by the Zigbee standard communication protocol 24, and checks the virtual communication data of the application layer, the packet is sent from the end device 01, Specifying the receiver as enddevice02, confirming that the second message packet is transmitted to itself by a certain name enddevice01 (but does not know the TCP/IP address of the other party), and finds that the instruction in the second message packet virtual communication protocol 10 is Turn off the unit. After parsing the packet, the target IoT device 72 executes the command in the virtual communication protocol 10 to perform a shutdown operation.

In this example, a packet transmitted by the IoT device 32 to the IoT host 60, which is transmitted by the virtual communication protocol, is referred to herein as a first message packet, and the first message packet includes at least the following architecture: "Virtual Protocol 10 (IoT Protocol):
